Problems such as unidentification, uncoordinated physical and spatial context of old and new districts of city, living environmental pollutions, living in suburbs, over centralization of official and non-official economic activities and therefore uncoordinated centralization of population in this city and so on, caused that population centers and margin cities of this megalopolis grew up and changed into population poles as the dormitory centers and hinterlands of Tehran that creation of Karaj urban pole in west of Tehran is the best example in this regard.
